- A
AWS Key Management Service (AWS KMS)
Why wrong: AWS KMS is a service for managing encryption keys, not SSL/TLS certificates. It cannot automatically provision or renew certificates for an ALB.
- B
AWS WAF
Why wrong: AWS WAF is a web application firewall that protects web applications from common exploits. It does not manage SSL/TLS certificates or handle HTTPS termination.
- C
AWS Certificate Manager (ACM)
ACM is the correct service. It provisions, manages, and automatically renews SSL/TLS certificates. ACM integrates directly with ALB at no additional cost, simplifying HTTPS configuration.
- D
AWS Secrets Manager
Why wrong: AWS Secrets Manager is designed to securely store and rotate secrets such as database credentials. While it can store certificate private keys, it does not natively integrate with ALB for HTTPS termination or automatic certificate renewal.
AWS Certificate Manager: No-Cost Automatic Certificate Renewal
This CLF-C02 practice question tests your understanding of security and compliance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company runs a web application on an Application Load Balancer (ALB) in the us-east-1 Region. The application serves HTTPS traffic. The company uses a third-party certificate authority to issue SSL/TLS certificates, but these certificates expire every year and require manual renewal. The company wants to use a managed AWS service to automatically provision, renew, and manage the SSL/TLS certificates for the ALB at no additional cost (no extra charge beyond the ALB usage). Which AWS service should the company use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS Certificate Manager (ACM)
AWS Certificate Manager (ACM) is the correct service because it can provision, manage, and automatically renew public SSL/TLS certificates for use with an Application Load Balancer at no additional cost. ACM integrates directly with ALB to handle certificate deployment and renewal, eliminating the need for manual renewal of third-party certificates. The service is free for public certificates used with supported AWS services like ALB, CloudFront, and API Gateway.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Key Management Service (AWS KMS)
Why it's wrong here
AWS KMS is a service for managing encryption keys, not SSL/TLS certificates. It cannot automatically provision or renew certificates for an ALB.
When this WOULD be correct
A company needs to encrypt data at rest in Amazon S3 using a customer-managed key with automatic annual rotation. AWS KMS would be the correct service to create and manage the CMK with automatic rotation enabled.
- ✗
AWS WAF
Why it's wrong here
AWS WAF is a web application firewall that protects web applications from common exploits. It does not manage SSL/TLS certificates or handle HTTPS termination.
When this WOULD be correct
A company needs to protect an ALB from SQL injection or cross-site scripting attacks, and wants to filter malicious web traffic. AWS WAF would be the correct service to deploy on the ALB for that purpose.
- ✓
AWS Certificate Manager (ACM)
- ✗
AWS Secrets Manager
Why it's wrong here
AWS Secrets Manager is designed to securely store and rotate secrets such as database credentials. While it can store certificate private keys, it does not natively integrate with ALB for HTTPS termination or automatic certificate renewal.
When this WOULD be correct
A company needs to store and automatically rotate database credentials or API keys used by an application. The question specifies a requirement for a managed service to rotate secrets on a schedule, and the candidate must choose the service that handles secret rotation without custom code.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓AWS Certificate Manager (ACM)Correct answer▾
Why this is correct
ACM is the correct service. It provisions, manages, and automatically renews SSL/TLS certificates. ACM integrates directly with ALB at no additional cost, simplifying HTTPS configuration.
✗AWS Key Management Service (AWS KMS)Wrong answer — click to see why▾
Why this is wrong here
AWS KMS is a service for creating and managing encryption keys, not for provisioning or renewing SSL/TLS certificates. It does not automate certificate renewal or integrate with ALB for HTTPS termination.
★ When this WOULD be the correct answer
A company needs to encrypt data at rest in Amazon S3 using a customer-managed key with automatic annual rotation. AWS KMS would be the correct service to create and manage the CMK with automatic rotation enabled.
Why candidates choose this
Candidates may confuse key management with certificate management, assuming KMS handles SSL/TLS certificates because both involve cryptographic materials.
✗AWS WAFWrong answer — click to see why▾
Why this is wrong here
AWS WAF is a web application firewall that protects against common web exploits, not a service for managing SSL/TLS certificates. It does not provision or renew certificates.
★ When this WOULD be the correct answer
A company needs to protect an ALB from SQL injection or cross-site scripting attacks, and wants to filter malicious web traffic. AWS WAF would be the correct service to deploy on the ALB for that purpose.
Why candidates choose this
Candidates may confuse AWS WAF with security-related services and think it handles certificate management, or they may associate it with HTTPS traffic protection without understanding its specific function.
✗AWS Secrets ManagerWrong answer — click to see why▾
Why this is wrong here
AWS Secrets Manager is designed to securely store and rotate secrets like database credentials, API keys, and other sensitive configuration data, not to manage SSL/TLS certificates for load balancers. It does not automatically provision or renew certificates for use with AWS services like ALB.
★ When this WOULD be the correct answer
A company needs to store and automatically rotate database credentials or API keys used by an application. The question specifies a requirement for a managed service to rotate secrets on a schedule, and the candidate must choose the service that handles secret rotation without custom code.
Why candidates choose this
Candidates may confuse Secrets Manager with ACM because both services involve 'secrets' and 'certificates' are also secrets. They might think Secrets Manager can manage SSL/TLS certificates since it handles other types of secrets, but it lacks the integration with AWS services for certificate provisioning and renewal.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse AWS KMS as a certificate management service because it deals with encryption, but KMS manages symmetric and asymmetric keys for data encryption, not SSL/TLS certificates for HTTPS termination.
Detailed technical explanation
How to think about this question
ACM automatically renews certificates issued by Amazon's public certificate authority (CA) approximately 60 days before expiration, using DNS validation or email validation to prove domain ownership. When associated with an ALB, ACM handles the SSL/TLS termination by deploying the certificate to the load balancer and rotating it transparently without any downtime. This automation is critical for production environments where manual certificate renewal can lead to expired certificates and service outages.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
